Answer:

Step-by-step explanation:

Alright, lets get started.

The formula for volume of the cone is :

V=\frac{1}{3}\ \pi r^2h

Please refer the diagram I have attached.

There is a right angle triangle formed.

Using Pythagorean theorem,

l^2=h^2+r^2

13^2=h^2 + r^2

h^2=169-r^2

taking square root on both sides,

h=\sqrt{169-r^2}

This is the answer h.

Hope it will help :)

Salsk061 [2.6K]

Answer:

Step-by-step explanation:

Adam plans to choose a video game from a section of the store where everything is 75% off.

The expression written by him for this situation is d - 0.75d.

Here, the part d represents the sale price before discount and the part 0.75d is the discount amount.

The expression written by Rena is 0.25d.

Here, the part 0.25d is the price after discount. Since 75% is the discount, the rate after disount is 25% and 25% of d is 0.25d.
